Momwe mungasinthire epoxy resin mu chubu cha epoxy glass fiber

Kapangidwe ka epoxy glass fiber chubu ndizovuta. Momwe mungapangire epoxy resin kukhala epoxy glass fiber chubu? Otsatirawa opanga ma epoxy glass fiber chubu adzakudziwitsani:

Zopangira zopangira epoxy glass fiber chubu ndi zomatira zomatira-zomata gawo lapansi ngati zinthu komanso zomatira zomwe zimagwiritsidwa ntchito nthawi imodzi.

Makamaka wamba galasi nsalu ndi pepala impregnated ndi phenolic utomoni kapena phenolic epoxy utomoni, thonje nsalu impregnated ndi utomoni womwewo angagwiritsidwe ntchito pa mlandu umodzi.

Panthawi yokhotakhota, zomatira zimadutsa muzitsulo zomangika ndi chowongolera chowongolera ndikulowa m’malo otentha kutsogolo. Pambuyo usavutike mtima ndi kukhala povutirapo, ndi bala pa chubu pachimake wokutidwa ndi filimu. The mavuto wodzigudubuza ntchito zina kumangika kwa chilonda zomatira zakuthupi. Kumbali imodzi, kupukuta kumakhala kolimba, ndipo kumbali inayo, chigawo cha chubu chikhoza kukulungidwa mothandizidwa ndi kukangana. Kutentha kwa wodzigudubuza kutsogolo kuyenera kuyendetsedwa mosamalitsa. Kutentha kukakwera kwambiri, utomoni umayenda mosavuta, ndipo kutentha kukakhala kotsika kwambiri, kumamatira kwabwino sikungatsimikizidwe.

Mukamagwiritsa ntchito njira yokhotakhota kuti muwumbe chitoliro, choyamba gwiritsani ntchito chotulutsa pachitoliro. Wotulutsa amatha kupangidwa ndi mafuta odzola, phula ndi sera yoyera pamlingo wa 1.5: 1: 1 atasakanizidwa ndikukhazikika. Mukamagwiritsa ntchito, gwiritsani ntchito turpentine kuti musungunuke mu phala. Chubu pachimake TACHIMATA ndi wothandizira kumasulidwa ayenera yokutidwa ndi gawo la zomatira zakuthupi monga backsheet, ndiyeno kuikidwa pakati pa tsinde ziwiri zothandizira ndi kuthamanga wodzigudubuza amaikidwa pansi kuti compress pachimake chubu.

Wongola zomatira chilonda pa mapindikidwe makina kuti zimadutsana ndi mbali imodzi ya filimuyo, ndiyeno mphepo izo pang’onopang’ono, ndi liwiro akhoza ziwonjezeke pambuyo yachibadwa.

Itha kuwongoleredwa pa 80-120 ℃ pozungulira phenolic chubu. Ikakulungidwa mpaka makulidwe anthawi zonse, tepiyo imatsekedwa, ndipo chubu chopanda kanthu ndi chubu chopanda kanthu chimachotsedwa pa makina opiringirira a chubu ndikutumizidwa ku uvuni kuti chichiritsidwe. Popanga phenolic coiled chubu, ngati makulidwe a khoma ndi zosakwana 6mm, akhoza kuikidwa mu uvuni pa 80-100 ℃, ndiyeno kutentha kwa 170 ℃ kuchiza kwa 2h. Mukamaliza kulimbitsa, chotsani mu uvuni, muziziziritsa mwachibadwa kutentha kwa firiji, ndipo potsiriza chotsani chitoliro pa chitoliro.
